碳纤维短切丝对水泥混凝土梁性能的改善试验研究

Experimental study on improvement of performance of cement concrete beam by carbon fiber short-cut

随着工程建设环境越来越复杂,混凝土材料抗裂与抗折性能不足的缺点也显得尤为突出.本文通过掺入碳纤维短切丝的方式改善混凝土梁抗折性能的试验,重点分析了达到最佳抗折效果时碳纤维短切丝的长度与掺量.试验结果表明,当掺入长度为6 mm,掺量为1.0%的短切丝时,对混凝土梁的抗折性能综合提升效果最佳.

With the increasing complexity of construction engineering environment,the shortcomings of concrete materials in crack resistance and bending resistance are particularly prominent.In this study,the flexural performance of concrete beams is improved by adding short carbon fiber strands.The length and amount of carbon fiber short strands are mainly analyzed to obtain the best reinforcement effect.When the length is 6 mm and the dosage is 1.0%,the bending resistance of concrete beams can be improved comprehensively.
